Embodiment Construction

[0013] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0014] The main cylinder of the double-supported shell shown in the attached figure includes a cylinder body 2 and two support cylinders 1 arranged at intervals along the busbar on the same side on the side wall of the cylinder body 2. The flanging is formed, and the intersection of the cylinder 2 and the support 1 is connected by a circular arc transition. The minimum distance between the flanges of the adjacent support 1 is L1≥8t (t is the wall thickness of the cylinder 2). In this embodiment, the cylinder 2 The wall thickness t is 10 mm, and the minimum distance L1 between the flanges of adjacent support tubes 1 is 80 mm.

[0015] Both ends of the cylinder body 2 are provided with outer bevels.

Abstract

The invention discloses a double-branch-cylinder housing main cylinder, which comprises a cylinder body, and two branch cylinders which are arranged along the same side busbar on the side wall of thecylinder body in a spaced manner, wherein each branch cylinder is formed by flanging a hole in the side wall of the cylinder body outwardly, and joints of the cylinder body and the branch cylinders are in arc transition connection; the minimum distance L1 between flanges of the adjacent branch cylinders is greater than or equal to 8t (t is the wall thickness of the cylinder body); and outer grooves are formed in two ends of the cylinder body. According to the double-branch-cylinder housing main cylinder, when one branch cylinder is being flanged, the adjacent branch cylinder cannot be deformed.

Description

technical field [0001] The invention relates to the field of high-voltage substations, in particular to a housing main cylinder. Background technique [0002] Some shells are provided with two support tubes on the main tube, and the two support tubes are arranged at intervals along the busbar on the same side on the side wall of the cylinder body. The main defect of the main tube of this shell is that the distance between the two support tubes is too close, and they will affect each other during flanging, which may cause serious deformation of the support tubes. Contents of the invention [0003] Aiming at the deficiencies of the prior art, this utility model proposes a double-support shell main tube that can avoid deformation of adjacent support tubes when the support tubes are flanged and stretched. [0004] The present invention achieves technical goals through the following technical solutions. [0005] The main shell of the double support tube includes a cylinder bo...
